To all whom it may concern:

Be it known that I, PHILIPPE BALDENs- PERGER, a citizen of the Republicof France, residing at St. Pi, (Vosges,) France, have in vented anImproved Manual Motor, (for which I have obtained the following patents:in France April 30, 1891, No. 212,173; in Belgium July 27, 1891, No,95,789; in Great Britain October 12,1891, No. 17,352; in Austria-Hungary October 11, 1891,No. 48,974 and No. 552; in Germany October14,1891, No. 66,479; in Spain August 31, 1891, No.12,392; in ItalyAugust 8, 1891, XXV, 30,175, and (addition) November 6, 1891, XXV,30,559; in Norway August 3, 1891,No. 2,473; in Sweden July 29, 1891, No.3,412 and (patent) (addition) October 23, 1891, No. 3,412; in RussiaOctober 9, 1891; in Turkey September 26, 1891, No. 240, and inSwitzerland October 2, 1891, No. 3,907,) of which the following is aspecification.

This invention has reference to motors designed to be actuated by manualeffort; and it consists in the simple and efficient arrangementhereinafter described, whereby a comparatively-high degree of power iscreated with but minimum exertion.

In the accompanying drawings, forming part of this specification, Figurel is a central vertical section of a manual motor embodying myimprovement, and Fig. 2 is a front view of the same.

The base of the motor-frame comprises two triangular castings S, formingbearings for the transverse shaft 0, upon one of the projecting ends ofwhich is keyed a band-pulley V, which may operate a belt to drive anydesired machinery. The base-castings S are braced at their top by atransverse rod b, and the upper part of the framing is constituted bytwo vertical standards e, connected and braced at their top by atransverse bar f. Centrally keyed on the transverse shaft 0 is aratchet-Wheel R, the teeth of which are ongaged by pawls B B, pivotallycarried by two arms K K, loosely mounted at one end on the shaft 0,while the other ends are pivotally secured to links 0 and c, in turnpivotally bolted to the lower end of the vertical lever a. The lever ais fulcrumed upon a rod h, bearing in a pair of arms D, rigidlyprojecting from the upper portion of the base-casting 8. The saddle Ahas a sleeve E, loosely mounted on an upper rodf, and dependingextension F of said sleeve being pivotally connected at g, to the levera through the medium of a link connection O. The upper end of the levera is provided with transverse handles M, and the arms D are providedwith a transverse foot-piece P.

The operation of this device will be obvious. The operator, seated inthe saddle A, rigidly braces his feet against the foot-piece P and canthen vibrate the lever a with comparatively-little exertion, themovements of the lever ct in either direction occasioning the rotationof the ratchet-wheel, and the consequent revolution of shaft 0 andband-pulley V, since the pawls B and B alternately engage saidratchet-wheel, and both serve to rotate it in alike direction. By havingthe saddleA pivoted and connected, as described, the exertion on thepart of the operator is not only materiallyreduced,but much is taken 0Eof body movements to secure the actuation of the device.

I claim- 1.. In a manual-motor apparatus, the combination, with thesupporting-frame, a driving-shaft journaled therein, and a ratchetwheelcarried thereby, of rod h, an actuatinglever pivoted thereto, a pair ofarms pivoted to one end of said lever, pawls thereon adapted to engagewith the teeth of said ratchetwheel, and a saddle pivotally mounted onthe main frame and having a link connection with the actuating-lever,substantially as set forth and described.

2. In a manual-motor apparatus, the combination, with the driving-shaftand pawland-ratchet devices located in the base of the 7 apparatus, ofarms D D, having the foot-rest In testimony whereof I have signed thisP, and rod h, and an actuating-lever a, pivotspecification in thepresence of two subscribed on said. rod and connected with the pawlingrwitnesses.

devices, together with a pivotally-mounted 7 PHILIPPE BALDENSPERGER. 5saddle having a link connection with the said Witnesses:
